The in-situ observation together with the Philae lander uncovered the mystery of the cometary nucleus of 67P\/Churyumov\u2013Gerasimenko. The VIRTIS-H is a spectrograph onboard the Rosetta orbiter which provides moderate-resolution (R~800) near-infrared spectra (2~5 micron) and was designed for studying the chemical abundances and space distribution of the inner atmosphere (d&lt;100 km) of comet 67P. So far, all the VIRTIS-H spectra are already released to the public. In this project, we propose using the VIRTIS-H data to search for the short-term variation of H2O\/CO2 emission and indicate the morphology and possible source region of narrow gas streams from the cometary nucleus. The narrow jet is a short-living phenomenon (&lt;1 hour) which had observed by the Rosetta OSIRIS instrument in the optical bandpass. We can better characterize the nature of cometary outbursts by combing the measurement from multiple instruments.<\/p>\n\n\n\n<p style=\"font-size:15px\">Background requirement:<br>basic Linux operation, ability to read\/write python scripts<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Localizing the Source of Gas Streams on Comet 67P by De &hellip; <a href=\"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/2023ssp-19\/\" class=\"more-link\">\u95b1\u8b80\u5168\u6587 <span class=\"screen-reader-text\">2023 #17<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"ngg_post_thumbnail":0,"footnotes":""},"class_list":["post-825","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/wp-json\/wp\/v2\/pages\/825","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/wp-json\/wp\/v2\/comments?post=825"}],"version-history":[{"count":4,"href":"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/wp-json\/wp\/v2\/pages\/825\/revisions"}],"predecessor-version":[{"id":1979,"href":"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/wp-json\/wp\/v2\/pages\/825\/revisions\/1979"}],"wp:attachment":[{"href":"https:\/\/www.astro.ncu.edu.tw\/taova\/index.php\/wp-json\/wp\/v2\/media?parent=825"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
